Binding datagrid using SQLite

I have a SQLite database that is being accessed by:

public IEnumerable<marketVendors> GetItems()
        {
            lock (locker)
            {
                return (from i in database.Table<marketVendors>() select i).ToList();
            }
        }

How can I bind this data to the datagrid?

Hi Garling Beard,

You can bind the SQLite database tables to SfDataGrid using the ItemsSource property in SfDataGrid.SfDataGrid.ItemsSource property. 

While setting the database table as List, SfDataGrid will not refresh the view automatically at runtime. Hence you can change the database table as an ObservableCollection that implements ICollectionChanged interface. In such case, SfDataGrid will automatically refresh the view when an item is added or removed at runtime. For more details about data binding please refer the below links of our user documentation.

http://help.syncfusion.com/xamarin/sfdatagrid/data-binding 

Please refer the below code example in which we have changed the database table into ObservableCollection and bound it as data source for the SfDataGrid.





//App.cs


public class App : Application

{   

    SfDataGrid sfGrid;

    public static SampleDemoDatabase database;


    public App()

    {

        // The root page of your application

           

        sfGrid = new SfDataGrid();

        sfGrid.ItemsSource = Database.GetItems();           

        Grid mainLayout = new Grid() { VerticalOptions = LayoutOptions.FillAndExpand };

        mainLayout.RowDefinitions.Add(new RowDefinition());

        mainLayout.ColumnDefinitions.Add(new ColumnDefinition());

        mainLayout.Children.Add(sfGrid, 0, 0);


        MainPage = new ContentPage

        {

            Content = mainLayout

        };


    }


    public static SampleDemoDatabase Database

    {

        get

        {

            if (database == null)

            {

                database = new SampleDemoDatabase();

            }

            return database;

        }

    } 
}

//OrderItem.cs


public class OrderItem

{


    public OrderItem()

    {


    }


    [PrimaryKey, AutoIncrement]

    public int ID { get; set; }

    public string Name { get; set; }

    public int TokenNo { get; set; }

    public string BillStatus { get; set; }

}

// SampleDemoDatabase.cs


public IEnumerable<OrderItem> GetItems ()

{

        lock (locker)

    {                             

        // Changing the database table items as ObservableCollection

        var table = (from i in database.Table<OrderItem>() select i);

        ObservableCollection<OrderItem> OrderList = new ObservableCollection<OrderItem>();

        foreach (var order in table)

        {

            OrderList.Add(new OrderItem()

            {

                ID = order.ID,

                Name = order.Name,

                TokenNo = order.TokenNo,

                BillStatus = order.BillStatus

            });

        }

        return OrderList;                                    

     }

}

Hi. Please, could you update your sample SampleDemo-641920397 for actual Xamarin and actual Syncfusion. I updated Nuget, but there are errors and nonfunctional part UWP. Could you bind to SQLite (dbase.db3) too. Thank you very much. Peter

Hi Peter,

Thank you for your patience,

We have prepared a sample for your query. In our sample we inserted data to the local database while launching the app and fetched the data from the local database while appearing the MainPage. For more details please refer to the below sample.
